.THREAD-GUiDE FOR LOOMS, 800.

EPECIFICATION forming part of Letters Patent No. 347,028, dated August 10,1886.

Application filed March 1, 1886. Serial No. 193,565. (No model.)

scription of the same.

The threads from the warpbeam usually pass up vertically and over the cradle-bar and draw off horizontally, or nearly so; hence if the threads are not separated before they pass over the cradle-bar,,the pressure mats them together so that they are very liable to subsequently be broken and the fabric injured by the mending of the warps. This is especially the case with silk.

By my invention the threads are separated as they pass up from the warp-beam before coming into contact with the first cradle bar or roller. This is effected by thin guide rings or disks, perforated to pass freely over the cradle bar or roller; and these guide-rings alternate with the threads, so as to separate them one from another and prevent them becoming matted togetherin passing over the cradle-bar. I prefer to taper or round the inner and outer edgesofthcse ri ngs,in orderto remove any burrs that might act to tear or injure the threads as they pass over the bar. These rings, being very thin, are adapted to the separation of the threads regardless of the gage or number of threads to theinch, the proper number of rings being placed upon the cradle-bar and the threads being laid between them.

In the drawings, Figure 1 is a section of the thread-bar and elevation ofa ring. Fig. 2 is a similar view, also showing the threads, bars, and rings in enlarged size for clearness. Fig. 3 isa plan view of part of the thread-bar rings and thread; and Fig. 4 is a section of a single ring, showing the tapered or rounded edges.

a is the thread-bar or cradle-bar spindle, which is mounted in a loom or knitting-machine in brackets secured to the cradle-bar in the usual manner, and the same is free to revolve.

b are the guide-rings, which I prefer to make of thin sheet metal, although celluloid or similar substances might be employed, and these rings are threaded upon the cradle-bar spindle and are slightly larger than said spindleand are free to revolve or move sidewise upon the said spindle. In order that the surface of the guiderings may be perfectly smooth, I prefer to taper or round the outer and inner edges, 1 2, of the guiderings. This may be done by dies. These guide rings Z1 separate the threads 0 one from another as they pass over the cradle bar spindle, the portion of the thread 0 coming up from the Warp-beam, and the portion 0* passing off to the guide and needles or harness of the machine, a single thread being placed between each pair ofguiderings.

I am aware that a bar with deep peripheral grooves, in which the threads pass, has been used; also, that disks between. which threads pass have been pressed against such threads by a spring. These are not adapted to the object desired byine, because they will not yield to allow knots or inequalities to pass freely.

I claim as my inventionl. The combination, with the cradle bar spindle or'thread-bar, of separate guide-rings around said spindle or bar, and adapted to move freely endwise thereof, and between which the threads pass and are kept apart, substantially as specified.

2. The combination, with the cradle bar spindle or th readbar, of loose separate guiderings threaded upon said spindle or bar, the outer and inner edges of which are beveled or rounded, substantially as and for the purposes set forth.

Signed by me this 23d day of February, A. D. 1886.

J. DALTON.
